LUBRICATING DEVICE; FOR SLIDE-VALVES.

SPECIFICATION forming part of Letters Patent No. 745,630, dated December 1, 1903. Application filed January 19, 1903. Serial No. 139,62llt. (Ila model.)

To aZ-Z whom it may concern:

Be it known that I, ADALBERT KOHN, works foreman, a subject of the Emperor of Austria- IIungary, residing at Pilsen, Bohemia, Ans tria-Hungary, have invented certain new and useful Improvements in Lubricating Devices for Slide -Valves, of which the following is a full, clear, and exact description.

The present invention relates to means for lubricating the faces of slide-valves, and its particular object is to apply the lubricating medium directly to the face of the valve. In order to attain this object, the oil is fed to the valve-face through the steam-ports by a series of injector-jets, so that the lubricating medium will be sprayed onto the face of the valve in spite of the steam-pressure existing in the ports.

In order to render the present specification easily intelligible, reference is had to the accompanying drawings, in which similar letters of reference denote similar parts throughout the several views.

I Figure 1 is a cross-section through a steamcylinder and steam-chest, showing the ar rangement of the lubricating-nozzles. Fig. 2 is a horizontal section through the steamchest, and Fig. 3 is a detail view showing the arrangement of a nozzle for inclined valvefaces.

According to the device illustrated in Figs. 1 and 2 the pipe b leads from the lubricator and passing through'the side wallsof a steamport ends in a nozzle 0., which may beprovided with two or more openings or jets. Each nozzle is located in a steam-port, and the oil will be directed by the same onto the face of the slide-valve, as will be readily understood.

In addition to the thorough lubrication of the valve-faces attained by this method of lubricating the steam entering the cylinders 4 will also be lubricated and will properly lubriwhole valve-face evenly.

I claim as my invention- 1. In combination with a steam-cylinder, valve and steam-port, of means for spraying the lubricating medium within the steamport directly onto the face of the valve, sub stantially as described.

2. In combination with a steam-cylinder, valve and steam-port, of means within the port for spraying the lubricating medium directly onto the face of the valve, substantially as described.

3. In combination with a steam-cylinder, valve and steam-port, of a nozzle located within the port for spraying the lubricating medium directly onto the face of the valve, substantially as described.

4. In combination with a steam-cylinder, valve and steam-port, of'a nozzle located within the port for spraying the lubricating medium directly onto the face of the valve, the said nozzle having a plurality of openings or jets, substantially as described.

In witness whereof I have hereunto set my hand in presence of two witnesses.

' ADALBERT KOHN.
